Monitoring challenges
Static monitoring
It is necessary to reconstruct the static deformation of the spans to understand the current state of the structure, especially during load tests.
Cost maintenance
Huge structures are very costly to monitor with cabled installations: wireless sensors are the optimal solution.
Dynamic monitoring
It’s necessary to monitor dynamic parameters like oscillations and accelerations to understand the behaviour of the structure.
Surrounding stability
Analyze the deterioration over time of the crucial structural parts of the bridge or overpass.
KEY PARAMETERS
Using Deck and Accelerometers it is possible to obtain a complete dynamic characterization of the bridge or overpass. Parameters as accelerations, dynamic displacements, modal frequencies and temperatures are constantly monitored.
Tiltmeters allow the analysis of the static of the structure. These sensors, therefore, allow monitoring of the angular variations caused by the subsidence of the ground and/or structural parts. With the use of more tiltmeters inline it is also possible to obtain the static deformation of a span.
With the use of Analog or Digital communication nodes, it is possible to expand this monitoring system with other non-native wireless instruments of geotechnical type.
Anomalies
You can analyse parameters like oscillations and accelerations caused by earthquakes or other anomaly events.
Modal analysis
You can monitor frequencies and natural modes of vibration of the structure.
Static monitoring
You can monitor the static parameters like inclination and the deformation of the deck, settlements, stress, expansion or contraction of cracks and joint displacements.
Vibrations trends
You can view all the trends of the parameters detected by the sensors such as displacement and acceleration.
Bridge IoT remote monitoring
These frequencies are purged from white noise such as traffic or anomaly heavy loads.
